SPECIFICATION forming part Of Letters Patent N0. 402,746, dated May 7, 1889.

Application iiled January 8, 1889. Serial No. 295,808. (No model.)

'To all whom, t may concern:

Be it known that I, PETER N. KoHLsAAT, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Vinegar-Generators, of which the following is a specification, reference being had therein to the accompanying drawings.

This my invention relates to certain improvements in vinegar-generators suspended on trunnions to be reversible, and more particularly to the construction and arrangement of the air-circulating vents, and it has been my object to provide such vents as will require no valves, and yet with reversing the generator-Cask will prevent mash or vinegar escaping; and with that objectin view my invention consists of the novel devices and combination of devices hereinafter described and specifically claimed.

In the accompanying drawings, Figure l represents a longitudinal vertical `section through the center of the generator, and Fig. 2 a sectional plan of the' same.

Corresponding letters of reference designate like parts in all the figures of the drawings.

A denotes the cash, being barrel-shaped and provided with diametrically-opposite trunnions a in its center for supporting the same in standard bearings B to balance and swing therein. This cask, near one end, is provided with three perforated diaphragms, C, D, and E, the space between the diaphragms D and E being filled with filtering material, such as charcoal, gravel, and sand. The upper head of the cask is provided with a bung-hole closed with a stopper, H, for filling the cask, and into the space between diaphragm E and the bottom of cask A is tapped into the side of the cask a faucet, L, and to the middle of the cask is attached a glass tube, M, for indicating the quantity of the mash contained in the Cask. Both heads of the cask are tapped for check-valves I and I of any usual construction, with valves that will open or close by their own gravity, each to be open while on top of the cask and to close with reversing the Cask.

Into the front side of the cask A, above and below the line of the trunnions a of the same, I bore holes to be vertically on opposing angles of about forty-five degrees to the staves or cylindrical wall of the cask, and into these holes I insert two tubes, J and J so as to cross each other. The mash will rise in the tube J to the same level as in the cask, which is a little below the top end of such tube, while tube J communicates with the space above the mash to admit atmospheric air, the oxygen of which will acidify the mash adhering to the shavings with which the cask is filled, when the nitrogen will rise and escape through valve I.

At intervals-say every four hours--the cask is to be turned upside down, which should be done alternately in the direction indicated by the arrows and in the direction opposite, so the tubes J J with each movement will follow the upper semicircle, when no mash or vinegar can escape through either one of these tubes J and J one of which alternately will act as an air-vent.

After the mash has been converted into vinegar in the manner above described by repeated reversals of the position of the Cask, the cask is allowed to stand in the position in which it is shown in Fig. l, and as the vinegar accumulates in the chamber below diaphragm E it is withdrawn through faucet L, all suspended matter being caught by the itering material F placed Abetween diaphragms D and E. I

It will be readily seen that the tubes J and J will provide air-vents close to the surface of the mash without wasting any mash when reversing the cash, thus obviating the use of valves in that location. By inserting a stave of sucient thickness to enable the boring of holes in an angular direction to place the in and out lets at the relative vertical positions, the same about as the ends of tubes J and J have been shown, these tubes may be dispensed with.

Vhat I claim is- A reversible vinegar-generator provided with tubes at its middle at a sufcient angular position for their in and out lets to be respectively above and below the line of the mash and crosswise to pass each other, so that one at a time will act as an air circulating vent, substantially asset forth.

In testimony whereof I affix my signature in presence of two witnesses.

PETER N. KOHLSAAT.
